摘　　要：随着特高压互联互通建设,网级电网出现交直流混杂的复杂电气岛电网架构,调度自动化系统的传统电气岛着色存在电气岛识别不足、实时性差、颜色冲突影响安全调度等问题。提出新的电气岛着色方法,先根据DFS轨迹确定设备的电气岛,再识别出电气岛轮廓,然后将电气岛轮廓渲染为雾团。该方法能有效解决传统电气岛着色问题,识别准确,实时性好,可直观展现大电网电气岛状态,直观反馈网络解列合并和负载减载对电网的影响,辅助调度员分析决策。该方法特别适合交直流混合电网,已在多个网省调EMS系统中应用,证明该方法正确有效。The traditional electric Island topology coloring algorithm of power grid dispatching automation system can not adapt to the increasingly complex new power grid architecture,which has some problems,such as insufficient identification of electric Island,poor real-time performance,color conflict and so on.In this paper,a new topology coloring algorithm of electric island is proposed.Firstly,the electric island of the equipment is determined according to the DFS algorithm trajectory,and then the contour of the electric island is recognized,and then the gradient contour is rendered as a fog.This algorithm can effectively solve the problem of traditional topology coloring,with accurate identification and good real-time performance.It can intuitively show the state of power grid,easily determine the impact of network splitting,merging and load shedding on power grid,and assist dispatchers to analyze and make decisions.This algorithm is especially suitable for AC/DC hybrid power grid,and has been applied in several EMS systems of provincial dispatching,which proves that this method is correct and effective.
